KEYS100 Ultramarathon
About This Event
Registration is open for the 19th Annual race across the islands of the Florida Keys--May 15-16, 2027. This chain of unique and inter-connected islands--some inhabited, some not--end in the City of Key West, just 90 miles from Cuba. This is a pavement race, with approximately 75% run on paved bike paths and sidewalks, parallel pedestrian bridges and portions of the old service road. The balance is run on the road shoulder facing traffic--and close to it. (Awareness and caution are paramount when running these sections.) The Florida Keys, known locally as "The Conch Republic", is a spectacular and laid-back sub-tropical paradise, surrounded by the turquoise waters of the Atlantic Ocean and Florida Bay/Gulf of Mexico. The Keys feature great fishing, kayaking, snorkeling and diving, hotels, resorts, B&B's and cuisine and cocktails to fit every budget. There is entertainment to fit every taste, important history and a unique culture, sunsets that will keep you spellbound, special events going on throughout the year including KEYS100, of course, and you don't need a passport to visit here! So, what are you waiting for? We've saved a space for you!
